VIRAL DETECTION
Coronaviruses can be detected by ELISA, Immunoflourescence test, Immunoblot and PCR (Roos, 2003; Chan et al., 2004; Maschinen et al., 2005; ECDC, 2020; WHO, 2020). For epidemiological purposes the virus have to be cultured prior to other techniques in order to obtain good results (WHO, 2003; Ren et al., 2004). However, cultural technique is not recommended for COVID-19 (WHO, 2020). The main techniques currently in use for both SARS-CoV and 2019-nCoV are the RT-PCR and ELISA (Leung et al., 2004; Ren et al., 2004; CDC, 2020; Wu et al., 2020) . Analysis of blood proteins has provided a helping tool for identification of biomarkers for evaluation SARS-CoVs although they are not essential diagnostics at point of care (Ren et al., 2004; Kang et al., 2005).
